Let AC be the ladder and BC be the wall . Then,

In right $△$ ABC,

$A{C}^2=A{B}^2+B{C}^2$

$A{C}^2=(2.5{)}^2+(6{)}^2$

$A{C}^2=\mathrm{42.25mama}$

$AC=6.5m$

Hence, the length of ladder is 6.5 m.

Explanation

Diameter of car wheel is 84 cm

Circumference of the wheel = 2*pi*r

= 2*22*.42/7

= 2.64 meter

Speed of the car is 72 kmph

Speed in m/sec is 72*5/18 = 20 m/sec

Distance covered in 11 minutes = 20*11*60 = 13200 meter

Number of revolutions in 11 minutes = distance covered in 11 minutes / circumference of the wheel

= 13200/2.64

= 5000 revolutions
